Powerplus 520 nozzles are a significant upgrade in fueling for ALH TDIs. They are nominally the same size as .205s, but flow more fuel because of superior tip design.
This set of 4 nozzles will work well in a stock TDI, providing about a 15 HP and 25 ft./lb. power increase. They will also work in chip tuned cars, although they may tend to smoke with a stock turbo and a chip. If you're not upgrading your turbo the Sprint 520s may be a better option on a manual-transmission TDI, and the PP357s may work better on an automatic.
These fit non-PD engined TDIs. They include injector seals.
